The function given is:
h(x) = 3x-19
we want to find the value of x that makes this function equal to 71. To do so, we will substitute h(x) with 71 and solve for x as follows:
h(x) = 3x - 19
71 = 3x - 19
3x = 71+19
3x = 90
x = 90/3 = 30

5. Combining like terms is similar to adding and subtracting whole numbers because you just add/subtract the numbers with the same variables. It's different because in normal adding and subtracting, you can do it with any whole numbers. But with combining like terms you have to make sure that each term has the same variable or else you can't add/subtract them.
Parallel lines are defined to be two lines that will never intersect even when they go on infinitely. Think of it like railroad tracks. The rails must always be parallel, or the train will gets stuck. By observing lines L and M, you'll notice both lines make perfect railroad tracks, and they will never intersect. These lines are parallel.
Answer:
Probability of choosing first girl = 11/20
Next one would be 10/19
11/20 x 10/19 = 11/38
Probability = 11/38
Answer: no; A 1 X 5 rectangle has a perimeter of 12 units and does not have an area of 6 units, so a counterexample shows that your friends statement is not correct
